Etymology

Noun

calorie (plural calories)

(nutrition) Kilogram calorie or large calorie. A unit of energy 1000 times larger than the gram calorie. It is equivalent to the gram kilocalorie, approximately 4.2 kilojoules.

(physics, chemistry, obsolete) The gram calorie or small calorie, a non-SI unit of energy, equivalent to approximately 4.2 joules. This unit was widely used in chemistry and physics, being the amount of energy needed to raise the temperature of 1 gram of water by 1 °C.

Usage notes

• Most scientific studies are now carried out using the joule (an SI unit).

• In nutritional contexts the term calorie refers to the kilogram calorie and the term kilocalorie refers to 1000 gram calories. Thus the two terms are equivalent.

• European legislation now requires foods to be labelled with the term kilocalorie.
